How to convert KB to MB

Divide kilobytes by 1024 to get megabytes in binary units. For example, 2048 KB ÷ 1024 = 2 MB. This is useful when an upload form sets a limit in MB but your file manager shows KB. If a form says 'max 500 KB', that is about 0.49 MB; UsefulTab's Resize Image to KB tool can help get a photo under it.
